    Aug 6, 2020 · Credit: NASA/JPL-Caltech/Lunar & Planetary Institute. In 1989, after a 12-year journey, a small human-made spacecraft known as Voyager 2 flew by the planet Neptune, and had a fruitful (though brief) encounter with an exotic and fascinating world: Triton. This small body, 2709 km in diameter, originated in the cold trans-Neptunian space occupied ...

    NASA's Voyager 2 is the second spacecraft to enter interstellar space. On Dec. 10, 2018, the spacecraft joined its twin – Voyager 1 – as the only human-made objects to enter the space between the stars. Voyager 2 is the only spacecraft to study all four of the solar system's giant planets at close range. Voyager 2 discovered a 14th moon at ...

    The discovery comes just as the Neptune encounter -- Voyager 2's fourth and final planetary flyby in 12 years -- officially ends today (Oct. 2). This is the first time geyser-like phenomena have been seen on any solar system object (other than Earth) since Voyager discovered eight active geysers shooting sulfur above the surface of Jupiter's ...

    Aug 25, 2009 · Triton was the last solid object visited by the Voyager 2 spacecraft on its epic 10-year tour of the outer solar system. Voyager mapped only the hemisphere that faces Neptune, but revealed a very young surface scarred by rising blobs of ice (diapirs), faults, and volcanic pits and lava flows composed of water and other ices.

    Aug 25, 2009 · Triton, Neptune's largest moon, was the last solid object visited by the Voyager 2 spacecraft on its epic 10-year tour of the outer solar system. The rugged terrain in the foreground is Triton's infamous cantaloupe terrain, most likely formed when the icy crust of Triton underwent wholesale overturn, forming large numbers of rising blobs of ice (diapirs).

    Feb 27, 2023 · Monday, February 27, 2023. Four hours and six seconds after they had been taken at Neptune, the images from Voyager 2 reached Earth in August 1989, and they showed something weird. Triton, a large moon that orbits Neptune backwards, opposite the direction that most of the other moons in the solar system do, had some dark splotches on its cold ...
